UNITED PATENT OFFICE 72,601,631 TURN-ACE v"WALL George P. fReintjes, Kansas'` City, Mo. Appear-ion 'July-7, 194.7, ser-isi No. 759,425

'1 This invention relates to boiler supports and enclosing Walls for that type of boiler having a fserie's of `boiler tubes :extending z in generally parallel relation to the enclosing .walls-'and capable of longitudinal expansion independently of Another object of the invention is to produce 'a lconstruction of the type vindicated Vwhich is effective, regardless of whether `'the boiler tubes expand upwardly or downwardly, depending upon which vend of the boiler is fixed.

With the general objects named in view and others as will hereinafter appear, the invention consists Qin certain novel and useful features of construction and organization of parts asherey inafter described and claimed; and in order that it may be fully understood, reference is to be 7 ,I v,had totrhe accompanying drawing, in which:

Figure is a fragmental vertical section o `through a boiler tube furnace embodying the l invention, in which the boiler tubes are mounted for downward expansion.

Fifurei 2 is a section on the line II-II of Figure 1,.

Figure 3 is a section on the line III-III of Figure 1 AFigure 4 is a fragmental vertical section .through ga slightly modified construction of the type shown in Figures 1 through 3.

-, Figure 5 is a fragmental vertical section through `a wall construction in which the boiler tubes are supported for upward expansion.

Figure 6 is a similar view, but of a slightly modified construction.

`supports `forming part of the skeleton framework of the furnace. Fixedly secured to the uprights or vertical supports 2, in any suitable manner,

are a plurality of tile or refractory 3 forming a furnace wall generally paralleling downwardly expansible boiler tubes lli. It is to be noted by reference to Figure 1 that the horizontal support projects beyond the plane of the end of (orizz-f6) the l'Wall 3, `such projecting portion in eifect constituting an extension from the horizontal or fixed wall support.

By preference the wall 3 comprises -a lseries of horizontal belts, predetermined tile 'of each belt being suspended from .hangers 5 which are supported by wall boxes 6, secured in any suitable manner to the uprights Y2, the wall being completed by a pair of plastic sealing coating's1'fand 8 if desired.

Below lthe fixed wall 3 a secondary wall or section movable with the tubes is provided, said lwall comprising a series of refractory or blocks in n i5 carried by bolts or the like I0 constituting wall supporting means, welded or fastened to and outwardly projecting from predetermined boiler tubes 4. The wall 9 may be held in position by'c'lampin'g rwashers II below clamping sleeves I`2 and fclamping nuts I3, the outer face of the wall being-finished by a plastic coating I 4, if

fdesired. In Figure 1, the yexpansion joint between the two wall 'sections is completed by securing an auxiliary horizontal beam I5y to the l. beam I,'sa`id` beam I5 supporting an angle iron yYI-Giftewhich a'wall box I1 is fastened. Detachably carried by the Wall box or support I1 are tile hangers I8 carrying a plurality of tile I9, 2B

' and 2I which overlap the upper end of the tube f' and tile wall 9 and provide an inwardly and downwardly opening expansion joint 22.

Figure 4 is much the same construction, the fixed s wall 23 being suspended from tile hangers 24,

and the upright furnace support 25 carries an inwardly projecting shelf 26 supporting a plurality of tile 21 and 28, overlapping the upper end of the tube and tile wall 29 to form an expansion joint 30.

Under some conditions it may be desirable to tie the lower ends of the tubes 4 to the furnace framework I-2 to insure that said tubes do not bow inwardly away from the furnace wall. A

construction of this nature is illustrated in Figure 1, in which outwardly projecting T-shaped angles or guide means 3| are welded or fastened to the tubes 4, the outer surfaces of the heads of said T-irons being in vertical sliding engagement with vertical angle plates 32 secured to the framework beam I, and being held in guided position by shouldered clamp plates 33, see Figure 2. This arrangement provides a tie-back for the tubes and limits their movement inwardly or outwardly in relation to the furnace. The

T @structure shown in Figure 1 may be completed by a shield to guard against air infiltration by welding T-irons 34 (see Figure 3) to predetermined tubes 4, the heads of said T-irons being the wall sections, said tile being carried bylar channel iron 40 or the like, rigidly secured in any suitable manner to said upright 2. In Figure 6, 4I and 42 respectively, indicate the movl able tube and tile wall and the fixed or suspended wall. In this construction a downwardly pro jecting plate 43 is secured to predetermined bolts 44 carried by the boiler tubes 4, and said plate may carry an extension plate 45 to which an inwardly opening channel 46 is xedly secured, Received within the channel 46 and bridging the expansion joint 41 between the two wall seotions, is an expansion joint sealing tile 48. Otherwise this construction may be similar to those previously described. 1

From the above description and drawing, it will be apparent that I have produced a construction embodying all ofthe features of ad vantage set forth as desirable, and while I have described and illustrated the preferred -embodiment, it is to be understood that I reserve the right to make all changes properly falling within the spirit and scope of the appended claims.

I claim:

l. In a Water wall furnace having a series of adjacent tubes exposed to the heat of the furnace, said tubes comprising vertically extending sections and angularly extending sections, a vertical metal framework externally paralleling and independent of the vertical section of the tubes, a series of tiles carried by the framework and forming a wall, a plurality of bolts welded to and 4 outwardy projecting from the angular sections of the tubes, tiles carried by said bolts and forming another wall, and an expansion joint formed between the walls by an overlapping of said walls, each wall being capable of independent movement without opening the joint.

2. In a water wall furnace having a series of adjacent tubes exposed to the heat of the furnace, said tubes comprising vertically extending sections and angularly extending sections, a vertical metal framework externally paralleling and independent of the vertical section of the tubes, a series of tiles carried by the framework and enclosing the tubes, a second series of tiles carried by the angular section of the tubes and enclosl ing the same, and an expansion joint formed by an overlapping of the two series of tiles whereby the two series' of tiles may shift without opening said joint.
